Owain Gwynedd

Owain ap Gruffudd (  23 or 28 November 1170) was King of Gwynedd, north Wales, from 1137 until his death in 1170, succeeding his father Gruffudd ap Cynan. He was called "Owain the Great" (Welsh: Owain Mawr) and the first to be styled "Prince of Wales". He is considered to be the most successful of all the North Welsh princes prior to his grandson, Llywelyn the Great. He became known as Owain Gwynedd (, "Owain of Gwynedd") to distinguish him from the contemporary king of southern Powys, Owain ap Gruffydd ap Maredudd, who became known as "Owain Cyfeiliog".
